University of Chinese Academy of Sciences, Beijing 100049, China Abstract Social media variety mainly concerns with the contents created and consumed in different online social network (OSN). Analyzing cross-OSN from the perspective of “variety” is beneficial to exerting the potential of big data, by integrally analyzing and exploiting the multi-sourced and multi-modal data. The problem of exploiting the cross-OSN data for comprehensive user modeling, which is fundamental in the context of multi-sourced social media big data was addressed. Inspired by the fact that the cross-OSN data shares unique user space, take the users as a bridge for associations mining between OSN was proposed. The discovered association patterns were then utilized in cross-OSN user demographic attribute inference and interest modeling in cross-OSN respectively, which can be further applied to personalized social media services.
